“…Variable reports about their CT-visibility exist [18,19]. Matsushita et al have shown that the density of hem-o-lok clip was 223 HU, consistent with its ex-vivo CT-based attenuation measurement [20]. In the current report, the density of the stone was 1609 HU and the stone analysis revealed calcium oxalate monohydrate, which explains the highly dense nature of the aggregate.…”

Highlights Foreign bodies, such as suture materials, mesh, cotton swab, Hem-o-lok clips, metallic clips, coils used for angioembolization etc. are rare causes of urinary tract stone disease. Clinicians should be aware of the possibility of migrated hem-o-lok clips serving as a nidus for urinary tract stone formation in patients who have undergone endoscopic PN. Attention to suture tension during endoscopic partial nephrectomy may reduce the risk of clip migration. Laser lithotripsy of the calculous cortical rim around the Hem-o-lok clip(s) and removal of the denuded foreign body under direct endoscopic visualization are strongly advisable, since Hem-o-lok clips are usually SWL-resistant.

“…To date, the Hem‐o‐lok® clip is the most widely used vessel‐sealing device in children [4–6]. One of the issues is radiological opacity of the operative site due to foreign body reaction, which would bother the judgment of radiologists in late postoperative time [7]. Moreover, the Hem‐o‐lok® clip is undegradable, and its long‐term retention in the body brings risks such as tissue inflammation, local adhesion and chronic perforation of tissues and organs [8, 9].…”

Objectives This study aims to evaluate the feasibility and safety of a 5-mm absorbable clips applied in thoracoscopic anatomical lung resection in younger children. Methods Demographic data and intra-and postoperative parameters of the two groups (Abs-o-lockÒ group and Hem-o-lokÒ group) were reviewed. In the Abs-o-lockÒ group, 5-mm absorbable clips were used in thoracoscopic anatomical lung resection on all patients from January 2020 to March 2021. In the Hem-o-lokÒ group, 5-mm Hem-o-lokÒ clips were used from January to December 2019. The primary outcomes were the one-time success rate of ligation, major bleeding rate, intraoperative dislodgement rate and operative time, which were compared between the two groups. Results There were 224 patients involved in this study, of whom 103 were in the Abs-o-lockÒ group and 121 were in the Hem-o-lokÒ group. The one-time success rate of ligation was 96.5% in the Abs-o-lockÒ group and 98.9% in the Hem-o-lokÒ group (p \ 0.05). No major bleeding occurred in either group. The intraoperative dislodgement rate did not significantly differ between the two groups (p = 1.0). The operative time consumed in the Abs-o-lockÒ group was much longer than that in the Hem-o-lokÒ group for subgroups of resection of extralobar sequestration (p \ 0.05), lobectomy (p \ 0.05) and segmentectomy (p \ 0.05). Conclusions Compared to Hem-o-lokÒ clips, it is feasible and safe to apply 5-mm absorbable clips for vessel sealing during thoracoscopic anatomical lung resection in younger children.

Objectives: This study aims to evaluate the feasibility and safety of a 5-mm absorbable clips applied in Thoracoscopic anatomical lung resection in younger children. Methods: Demographic data and intra- and postoperative parameters of the two groups (Abs-o-lock group and Hem-o-lok group) were reviewed. In the Abs-o-lock group, 5-mm absorbable clips were used in TALR on all patients from January 2020 to March 2021. In the Hem-o-lok group, 5-mm Hem-o-lok clips were used from January to December 2019. The primary outcomes were the one-time success rate of ligation, major bleeding rate, conversion rate, dislodgement rate and operative time, which were compared between the two groups. Results: There were 224 patients involved in this study, of whom 103 were in the Abs-o-lock group and 121 were in the Hem-o-lok group. The one-time success rate of ligation was 96.5% in the Abs-o-lock group and 98.9% in the Hem-o-lok group (p<0.05). No major bleeding occurred in either group. The conversion rates of the two groups were not significantly different (0/103 versus 2/121, p=0.55). The dislodgement rate did not significantly differ between the two groups (p=1.0). The operative time consumed in the Abs-o-lock group was much longer than that in the Hem-o-lok group in terms of subgroups of RES (resection of extralobar sequestration, p<0.05), lobectomy (p<0.05) and segmentectomy (p<0.05). Conclusions: Compared to Hem-o-lok clips, it is feasible and safe to apply 5-mm absorbable clips for vessel sealing during thoracoscopic anatomical lung resection in younger children.
